摘要: 为明确河南省洛阳市测报灯下昆虫的种群结构和主要农作物害虫发生动态,在2018—2022年连续5a利用佳多智能自动虫情测报灯对诱集到的昆虫种群结构和主要农作物害虫发生动态进行了分析。结果表明,5 a共诱集到昆虫239 793头,分属6目22科133种,其中,农作物害虫228 637头,分属4目17科96种,天敌昆虫11 156头,分属3目5科37种,就个体数量而言,害益比为95.34∶4.66。诱集到的农作物害虫以鳞翅目昆虫最多,占诱虫总量的60.56%,其中夜蛾科和螟蛾科为优势科,二点委夜蛾、甜菜夜蛾为优势种,东方黏虫、劳氏黏虫为丰盛种,银纹夜蛾、棉铃虫、小地老虎、双委夜蛾、玉米螟、桃蛀螟、黄地老虎、斜纹夜蛾和灰歹夜蛾为常见种;其次是鞘翅目昆虫,占诱虫总量的33.56%,其中丽金龟科为优势科,铜绿丽金龟为优势种,暗黑鳃金龟、大黑鳃金龟为常见种。优势种、丰盛种发生盛期分别为:铜绿丽金龟5月下旬—6月中下旬、二点委夜蛾6月中旬—9月中旬、甜菜夜蛾6月中旬—9月下旬、东方黏虫5月下旬—8月下旬、劳氏黏虫6月上旬—10月中旬。根据害虫优势种的发生动态,可在不同时间对优势种进行重点精准测报和防控。

Abstract: In order to make clear the insect population structure and the occurrence dynamics of major pests under forecast lamp in Luoyang City,Henan Province,from 2018 to 2022,for five consecutive years,the Jiaduo Intelligent Automatic Insect Information Forecasting Light was used to analyze the population structure and main pest occurrence dynamics of the trapped insects.The results showed that 239 793 insects were attracted in five years,belonging to 133 species of 22 families in six orders,and contained 228 637 agricultural pests,belonging to 96 species of 17 families in 4 orders,and 11 156 natural enemies belonging to 37 species,of 5 families in 3 orders, and the proportion of pest and natural enemy was 95.34∶4.66.Lepidoptera was the main pest of crops,accounting for 60.56% of the total number of trapping insects,of which Noctuidae and Pyralidae were the dominant families,Athetis lepigone and Spodoptera exigua were the dominant species,Mythinma separata and Leucania loreyi were the abundant species,and Argyrogramma agnata,Helicoverpa armigera,Agrotis ypsilon,Athetis dissimilis,Pyrausta nubilalis,Dichocrocis punctiferalis,Agrotis segetum,Spodoptera litura and Diarsia canescens were the common species;The next was Coleoptera,which accounted for 33.56% of the total number of trapping insects.Among them,the Rutelidae family was the dominant family,Anomala corpulenta was thedominant species,and Holotrichia parallela and Holotrichia oblita were the common species.The peakperiods of the dominant species and the abundant species were respectively:the A.corpulenta was from late May to mid‑June,A.lepigone was from mid‑June to mid‑September,S.exigua was from mid‑June to late‑September,M.separata was from late May to late August,and L.loreyi was from early June to mid‑October.According to the occurrence dynamics of the dominant species of pests,it is possible to focus on prediction and prevention and control of dominant species at different time.
